Chas, The K2 noise blanker works well on impulse type noise (like gasoline engine impulse noise or lightning static), but it is not effective on noise that has a slower rise time such as general atmospheric noise.
I would suggest the KDSP2 noise reduction algorithms as a potential better solution for the noise you are encountering. 73, Don W3FPR On 12/23/2010 9:29 PM, Owen B.
